A former Sinn Féin councillor who waterboarded and threatened to kill a man who he believed was trying to defraud him was not a friend of Sinn Féin TDs Mary Lou Mc Donald and Gerry Adams, the Special Criminal Court was told today.

Last month footage recorded on a mobile phone was shown to the court of Jonathan Dowdall (38) wearing a balaclava and holding a tea-towel to the man's face before pouring water over his head.

Jonathan Dowdall.

The court heard that Dowdall believed the victim, Alexander Hurley, was pretending to be a barrister and that he was seeking Dowdall's bank details in order to defraud him.

The two men had met after Dowdall had advertised a motorbike for sale on donedeal.ie.

Dowdall, with an address at Navan Road, Dublin 7 and his father Patrick Dowdall (59), of the same address, had both admitted to falsely imprisoning Mr Hurley by detaining him without his consent at Navan Road, Dublin 7 on January 15, 2015.

Both men had also pleaded guilty to threatening to kill Mr Hurley at the same place on the same date.

Today Mr O ‘Higgins submitted to the court that a number of issues had arisen and the court should take them into account before passing sentence.

He said that his client did not invite Mr Hurley to dinner, but Hurley was coming to the house with a receipt. Counsel said that there had been suggestions that his client was a leading member of the IRA and a friend of Mary Lou Mc Donald and Gerry Adams and this was not accepted by his client.

Mr O’ Higgins said that Mr Hurley had previous convictions for dishonesty and his word was can’t be accepted.

Ms Justice Isobel Kennedy, presiding, said that in light of the submissions the court would adjourn the sentence until May 30 next.

Last month Detective Inspector William Hanrahan, of the Special Detective Unit, summarized the facts of the case.

He told prosecuting counsel Vincent Heneghan SC that on March 9 last year Gardaí were searching Jonathan Dowdall's house on the Navan Road, in relation to a separate matter, when they found a USB flash drive.

When Gardaí examined the flashdrive, they discovered that it contained footage of a man imprisoned in Dowdall's garage, the court heard.

The victim, Alexander Hurley, was located by Gardaí on May 28 last year, and he gave a statement about the incident.

The court heard that on January 1 2015, Mr Hurley contacted Jonathan Dowdall through donedeal.ie about a motorcycle Dowdall had advertized for sale.

Mr Hurley expressed interest in the motorbike and on January 12 he met with the Dowdalls in their house, where he was shown the motorbike.

Later he was contacted by Jonathan Dowdall. They discussed the purchase. Mr Hurley said that he was waiting for a loan from the Credit Union.

On January 15, Mr Hurley got a phonecall from Jonathan Dowdall, who invited him to dinner at his house that evening.

Mr Hurley told the guards that he thought the invitation was a "bit unusual" but that Jonathan Dowdall insisted Mr Hurley attend, saying that his father had enjoyed his company.

That night, Mr Hurley went to the house.

He told the Gardaí that as soon as he arrived he was pushed into the garage and backed into a swivel-chair by Patrick Dowdall.

He was "petrified", he said.

He was tied to the chair with cable-ties and told by Patrick Dowdall that he was a "lying bastard from the sewer".

Patrick Dowdall told Mr Hurley that if he wanted to get out alive he better tell Jonathan what he wants to hear.

Mr Hurley, the court heard, was left alone in the garage and he heard the Dowdalls discussing what to do with him.

They said they would feed him to the dogs, chop him up and store him in a BMW if he didn't tell the truth.

When they returned, Jonathan Dowdall was wearing a balaclava and he asked Mr Hurley to tell the truth and called him a thief.

A person appeared at the door with a bucket of water and a tea-towel.

Jonathan Dowdall put the tea-towel over Mr Hurley's face and poured a full bucket of water over his head, the court heard.

Another bucket of water was poured over his head and he was told he had one more chance to tell the truth.

He was told he was not a barrister, that he was a fraudster, and that he would be chopped up and brought to Tyrone.

The court heard that he was told he was a "stupid dumbfuck to mess with the head of the IRA" and that Jonathan Dowdall was a "good friend of Gerry Adams and Mary Lou McDonald".

He was told if he contacted Gardaí he would be killed.

Patrick Dowdall threatened to pull off his fingers one by one with a pliers.

Mr Hurley told the guards that the Dowdalls were asking him why he had sought Jonathan Dowdall's bank details and that the father and son were concerned Mr Hurley was trying to defraud them.

The entire ordeal, the court heard, lasted for three hours.

Three video clips, recorded on a mobile phone, were shown to the court.

The first of three clips, from January 12 2015, showed Mr Hurley trying on motorcycle gear in the Dowdalls' garage.

In the second and third clips, from January 15, Mr Hurley was seen bound to a swivel-chair in the garage. The swivel-chair had been pushed to its side and Mr Hurley's head was on the floor.

The video showed Jonathan Dowdall hold a tea-towel over Mr Hurley's face and pour a bucket of water over his head.

The former councillor repeatedly asked Mr Hurley, "What were you going to do with my bank details?"

Mr Hurley said that he had applied for a loan.

Jonathan Dowdall said, "I'm going to cut you up piece-by-piece."

"Please don't hurt me," Mr Hurley said.

The court then saw Jonathan Dowdall use an electric razor to shave Mr Hurley's head. He asked again, "What were you doing with my bank details?"

He told Mr Hurley, "It's all over Facebook you're one of the biggest conmen going."

Jonathan Dowdall held Mr Hurley down and poured another bucket of water over his head.

Later, the swivel-chair was lifted up.

Patrick Dowdall was heard saying, "I'm going to start with the little one and work my way up to your thumbs."

The court heard that neither Jonathan nor Patrick Dowdall have any previous convictions.

Michael O'Higgins SC, for Jonathan Dowdall, and Michael Bowman SC, for Patrick Dowdall, told the court that their clients wanted to apologize for the violence and threats inflicted on the injured party.

The court heard that Jonathan Dowdall, a married man with four children, is a qualified electrician who in 2007 went into business himself, securing contracts with Bank of Ireland and G4S, a security company.

Mr O'Higgins said that he is "a man who lives for his family and has invested very heavily in his family".

The barrister said that after meeting Mr Hurley his client he had searched online and discovered that a number of complaints had been made regarding transactions with Mr Hurley. There was a reference to a man who had sold a car and was paid by Mr Hurley in a Euro cheque but the cheque had bounced.

Mr O'Higgins said that Dowdall was under huge pressure and that his business depended on a good credit rating.

He wanted to frighten Mr Hurley, the court heard, into not using his bank details.

The court also heard that Mr Hurley's profile on LinkedIn showed the official logo of the Law Library and stated that he was a barrister since July 2011.

Detective Inspector Hanrahan agreed with Mr O'Higgins that Mr Hurley is not a barrister.

Mr Hurley has two convictions for fraud.

In a victim impact statement, read to the court by Mr Heneghan, Mr Hurley said that it was a "brutal and heinous act of crime" and that his "life has turned into a tower collapsing".

He said that he has lost his job and his friends and that the "psychological injuries will never heal completely."
